I have no dog in this fight, so to speak, but I bet you already know whether video games vs getting to hunt again some time compares. Many folks in the same boat as you, nothing new. Have you thought about a once a year out of state hunting trip, like elk in Colorado if they are old enough? Assuming your kids are very young, since you're considering VG. I guess I am a bit surprised that a man that made it through BOOT and continued on would give up? May be time to "adapt and overcome"
BTW, I have hunted public before and after the 1st or second weekend it was quite dead as far as hunters go. I hunted Corps land around lakes, mainly around lake whitney. A lot of deer and some thick stuff, also a lot of turkey back then. I think now you have to get a day permit from the corps office IDK.
Don't give up, teach those kids perseverance and patience. I had a cousin that was in the corp, a Marine Gunner iirc, he said marines never quit, is this true?
